Title: Reinforcing fibers and method of producing same corona treatment of thermoplastic fibers
IPC: D06M13/02
Filed: 1979-07-06
Abstract: Reinforcing fibers of plastic having a surface tension of from 40 dyn/cm to about the surface tension of water are disclosed. The fibers can be easily and uniformly disposed in matrices. For organic matrices, a surface tension of 40-50 dyn/cm is effective. For cement matrices, a surface tension about 70-75 dyn/cm is effective. The high surface tensions are obtained by a corona treatment and subsequent application of a hydrophilic avivage. Corona treatment may be performed on the fibers, or on films from which the fibers are made.

Title: Apparatus and method for working on successive segments of sheet material
IPC: B65H20/10
Filed: 1979-12-26
Abstract: Apparatus for cutting successive contiguous segments of a lay-up of sheet material 12 has a table 14, an endless conveyor 18 to position the lay-up in the cutting zone of the table, and a carriage assembly 30, 24 which moves a cutting mechanism 32, 34 relative to the table in cutting engagement with the lay-up to cut patterns in response to a programmable controller 28. An encoder 40 on the carriage assembly detects movement of the latter, relative to the conveyor, returning to its starting position after a cutting cycle, and response means 42 energises the conveyor drive motor 20 in response to the detected movement to move the lay-up in the return direction through a distance related to that traversed by the returning carriage assembly, whereby the next segment of the lay-up is accurately positioned on the table. Error sensing means 43 detects an error in positioning the lay-up and alters the data in the controller to nullify the error.

Title: Fail-safe brake linkage for a vehicle with a hydraulic or pneumatic brake system.
IPC: B60T17/18
Filed: 1981-07-17
Abstract: The fail-safe brake linkage includes a hydraulic cylinder acting upon first levers. The first levers are rotatably mounted on a respective shaft. Also rotatably mounted to each shaft is a plurality of levers connected to brake activation rods. Each first lever is biased against a respective cylinder rod of the hydraulic cylinder.

Patent ES-8505113-A1 (ES)
Title: Enzyme chromatographic immunoassay.
IPC: C12Q1/26
Filed: 1983-07-14
Abstract: Chromatographic immunoassay employing a specific binding pair member and a label conjugate which delineates a border whose distance from one end of the chromatograph relates to the amount of analyte present. By combining the label conjugate and sample in a solution and immunochromatographing the solution, or employing a combination of enzymes, one enzyme being the label and the other enzyme affixed to the chromatographic support, the position of the border defined by the label can be related to the amount of analyte in the sample solution. Preferably, an immunochromatograph is employed having both a specific binding pair member and an enzyme affixed to the support. A sample is chromatographed and the amount of analyte is determined by (1) contacting the chromatograph with a second enzyme conjugated with a specific binding pair member which binds to the chromatograph in proportion to the amount of analyte bound to the chromatograph, or (2) including the second enzyme conjugate with said sample, resulting in a defined border related to the amount of analyte in the sample. The two enzymes are related in that the substrate of one is the product of the other, so that upon contact of the chromatograph with appropriate reagents, a detectable signal develops which permits detection of the border to which the analyte traveled. This distance can be related to the amount of analyte present in the sample.
